tended to be employed. with firearms of the.

character disclosed 1nmy copending` applications, Sr. No. 282,642, filed March 14, 1919, and Sr. No. 297,283, filed on even date herewith, although it is to be understood that the invention in many of its aspects may be adapted to various types of pistols, rifles, machine guns and other irearms.

lThe principal objects of the invention are to provide means for controlling the action of a firearm which is simple and substantial in construction, which may be manur'actured at a relatively low cost, which involves a minimum number of parts, which may be readily ,assembled and disassembled without the use of tools, and which is safe and reliable in use.

Another object is to provide means lfor automatically retaining the breech mechanism of an automatic firearm in retracted position after the last cartridge contained in the magazine has been fired, and to associate this means with the trigger in such manner that the automatic' operation of the firearm may be continued after a lled or partially filled magazine has been substituted forz the empty magazine merely b y pulling the trigger again. A corollarial object 'is to stop the automatic action-.of the firearm. at any .instant merely by releasing the trigger.

Another object is to provide improved safety means for locking the breech action so that -the gun will not fire even though the trigger be .pulled and to 'arrange the safety means so that it is effective under all con' ditions and is convenient to operate.

A further object is to correlate the parts of the control mechanism in such manner that the parts mutually cooperate to hold themselves in assembled relationship, thereby eliminating the necessity of separate holding means such as the bolts and screws ordlnarily provided, and to arrange the parts so that they may be readily detached from each other and from the frame of the rearm without the use of tools.

Another object is to provide means for detachably securing to a firearm magazines of diierent types, as for example a drum magazine sliding into the firearm from the side or a box magazine sliding into the firearm from the bottom, and to provide a single means for latching a magazine of either type in position.

Otherobjects of the invention will be apparent from the following description and accompanying drawings, in which- Figure 1 is a side elevation of the firearm completely assembled, showing a magazine of the drum type attached thereto;

The particular embodiment of' the invention chosen for the purpose of illustration within the receiver is described and claimed in my prior application Serial No. 282,642. The extractor and ejector mechanism associated with the bolt and receiver is described and claimed in my co-pending application Serial No. 297,284. Magazines of the types shown in Figs. 1 and 4 respectively are describedv and claimed in my co-pending applications Sr. No. 297,285, and Sr. No. 297,286, both filed on even date herewith. The present application is particularly directed to the frame F and the associated control mechanism which coperates' with the breech closing mechanism and the magazines. l ,A l

rI he frame'F is slidably connected to the receiver R by means 'of guides 43 and 44 In generaltheA control mechanism comprises (Fig. 7 fitting into grooves in the opposite sides of the receiver, the frame slidlng on to the receiver from the rear and being retained in position by the plunger catch 45. The frame F is provided with a chamber adapted to contain the control mechanism.

The bottom of thereceiverl and the top of' the frame 'areg provided with registering openings to permit a part of the control mechanism to extend upwardly from -the frame -into operative'relationship withthe breech closing `mechanism in the receiver.

ai tri r T,a sear S, a disconnector. D7 a .zyoke Y a catch'K, a safet catchS anda I `combined supporting an 'locking mem-1 45 Y Thee-member L comprisesan elongate ber L.

Vplate adapted to lie alonlgm'the right-hand side of the frame F and tending inwardly from this plate through alined openings 2' and 3 in the opposite,

walls ofthe frame.` The member 'also has a spring finger '4 extending rearwardly to the safety catch S'. The'sear S is pivota clockwise direction about this shaft by... means of a spring 6. The .trigger T isfpro vided on its left side with a recess 7 shaped to receive the disconnector D. The disoon nector D has a pivot lug extendi'ng'into a bearing opening 71 inthe trigger so 'as to be moved relatively tothe trigger either ULJUIVII into theinoperative position shown in Fig. 4 or into the operative position shown in Fig. 6. A spring 8 is provided normally to urge the disconnector into the position shown in F 6. The disconnector is provided with a projecting lug 9 which is adapted to engage against the curved face 1() of the sear when the trigger is pulled with the disconnector in the operative position shownin Fig. 6. The yoke Y surrounds the upper portion of the trigger T and is pivotally mounted on opposite sides of the trigger on lthe same shaft 2 upon which the trigger 4is mounted. A finger 11 projects from the for# ward end of the yoke through an opening in the forward kside of the frame F into position to be engaged by a member 12 mounted on the follower 13 of a magazine such as shown at M in Fig. 4, the construction of this magazine lbeing described and claimed in my co-pending application Serial No 297,286..

-'1,`h e safety catch S comprises a shaft .extending'A through alined openings 14 in the opposite sides of the frame F5 On the lefthand side of the frame the shaft is provided L. Half ofthe shaft is cut away through the portion extending across the,chamber in the frame F so' that .when the" handle 15 extends rearwardly as shown in Figs. 1 an'd 3 the cut-away' side of'fthe shaft faces 'rearwardly (Figs. 3 and 4) and when the handle 15'isrotated Ithrough 180.o to extend forwardly the cut-away portion faces for- `wardly ig. 6). The, rear end of the sear S is provided wlth a transverse semi-circular groove adapted to receive the remaining half of the shaft when the Sear is in itsoperative positionas shown in Fig. 4. When the safety catch is rotated i'nto the position shown in Fig. 6, it-completely disengages the sear so that the sear may be move intotheinoper- 'ative' position as shown in Fig. 6.

The forward end` of'the'frame F ,shown in elevation in Fig. 7, is provided with a '.:vertical guideway 17, having overhanging vflanges A18 and 19, adapted to receive the e 39v of ama zine of the t pe shown in 4 and 8. he receiver 1s provided I "withan opening 20 adapted vtoreceivefjiheL upper end of amagazine either of the type f2- shown in 1 or. of the typefshown in Fig. 4. This opening is provided with horitypeshown'in Fig. 1, the grooves 21 and 22.

4Zzontal.''grooves 21 and 22 adapted to receive l 'the guides 23v and 24 on the magazine of the extending entirely across the receiver so that the magazine may be inserted or removed from either side or inserted from one side and removed from the other side. The forward end of the frame F is provided with a horizontal channel 25 near its lower end toreceive a latch member 26 on the .magazine M which is adapted to coperate with the catch K to hold the magazine in position.

The catch K comprises an L-shaped lever extending along the left-hand side of the frame as shown in Figs. 1, 3 and 7. This lever is provided with an integral shaft 27 adapted to extend into an opening 28 in the frame F. As shown in Fig. 3 the opening 28 is considerably larger than the shaft 27 thereby providing an annular space between the shaft and the wall of the opening. The right-hand end of the shaft is joiirnaled in the right-hand side of the frame F and the left-hand end of the shaft is provided with an enlargement 29 which fits into the opening 28. Disposed in the annular space between the shaft 27 and the wall of the opening 28 is a coil spring 30, one end 31 of which is anchored in the enlargement 29 and the other end 32 of which is bent outwardly to extend into a groove 33 which extends along the rear .side of the opening 28.. The lower end of the catch K comprises a portion v34 which extends rearwardly, a portion 35 which extends inwardly, and a portion 36 which extends forwardly through an opening 37 i'n the frame F. The portion 36 projects somewhat into the guideway 17 so as to hook into an openin 38 in the guide 39 of the magazine l igs. 4 and 8). rhe spring 30 ur es the catch K in a clockwise direction ig. 1)

into engagement with the magazine, the portion 34 of the catch coperating with the catch 26 of the magazine of the type shown in Figs. 1 and 9 to hold the magazine against horizontal movement in guideways 21 and 22 and the portion 36 of the catch hooking into the opening 38 of the magazine of the type shown in Figs. 4 and 8 to hold the magazine from sliding downwardly out of the guideway 17. The lower edge 40 of the portion 36 of the catch is beveled as Vshown in Figs. 4 and-.6 so that the catch is aut'omatically moved out of the Ipath of the guide 39 ofthe magazine M ig. 4) when the magazine is moved upwardly into position, and the catch is returned to its normal position by the spring 30 after the opening 38 in the magazine guide comes into alinement with the portion 36 of the catch. The'latch 26 on the magazine M is beveled on both sides as shown in Fig. 9 so that the catch K is automatically retracted when a magazine Vof the type M shown in Fig. 1 is moved into position from either side, the spring 30 snapping the catch into holding position when the magazine is in place as in the case of a magazine of the type shown in Fig. 4.

As shown in Figs. 1, 3 and 7 Athe shaft 2 projects from the left-hand side of the frame over the catch K and the end of this shaft is provided with an under-cut recess 41 adapted to permit the vcatch to rotate in a counter-clockwise direction l(F ig. 1) a sufficient distance to disengage' the magazines but not a suliicient distance to permit the portion 36 of the catch to be withdrawn from the fopening 37 in the frame. However, when the shaft 2 is removed from the frame the catch may be rotated in a counter clockwise direction a sufficient distance to permit the portion 36 to leave the opening 37 whereupon the catch K may be removed to the left from the frame together with both the shaft 27 formed integrally therewith and the spring 30 which is anchored to the enlargement 29.

From the aboi'e description it will be evi dent that to attach the magazine of the type shown in Fig. 1 it is merely necessary to slide the magazine horizontally7 into place` from either side until the catch i snaps inte latch 26 and to attach a magazine of the` type shown in Fig. 4 it is merely necessary to slide the ma azine upwardly into place until the catch 1% snaps into the opening 38. To detach either magazine it is merely neces- Y sary to rotate the catch K by means of handle 42 a suiiicient distance in a counterclockwise direction to disengage the catch from the magazine whereupon the magazine may either be manually removed or in the case of a magazine of the type shown in Fig. 4 the niagazine may slide out by gravity. A

-To disassemble the parts the frame F is slipped off of the receiver from the rear, the

catch 45 first being pressed upwardly out ofthe path of the frame F. The spring linger 4 (Fig. 5) is then sprung out of the groove 16 of the safety catch S whereupon the safety catch may be withdrawn from theleft-hand side of the frame and the member'L carryingv the shafts 2 and 3 may be withdrawn from the right-hand side of. the frame. After the shafts 2 and 3 have been removed the sear S, trigger T, disconnector D and yoke Y will drop out upon inverting the frame F. The springs 5, 6 and A8'lare preferably anchored in the sear and the trigger respectively by expanding the last turn of each sprin so that it will tightly engage the peripheral wall of the circular recess into which it lits. After the shaft 2 has vheen removed as aforesaid the catch K may be rotated in a counter-clockwise direction until the portion 36 (Figs. 4 and 9) completely clears the opening 37 in the frame whereupon the catch may be withdrawn from the left-hand side of the frame as above mentioned. I

To reassemble'the parts the trigger T,

yoke Y, disconnector D and vsear S are dropped into the frame approximately in' their normal positions, andafter first tensioning the sprin'g30 by winding the free end 32 around the shaft 27 the catch K is applied by inserting the shaft 27 in the opening 38vwith the end 32 of the spring sliding in the groove 33. After the catch has been moved inwardly' against the side of the frame the catch is permitted to be rotated in a clockwise direction by means of the spring -30 until the portion 36 passes into the opening 37 and the portion 35 en` gages the receiver. The member L is ap-v plied byinserting the shafts 2 and 3 through the openings 2 and 3 in the frame and through the bearing openings in the yoke Y, trigger T and scar S respectively.` The safety catch S is then inserted into opening 14 and when in normal position the end of spring 4 snaps into the groove 16 thereby locking all the parts together.

The operation of the control mechanism is as follows: Assuming the :bolt to be held in retracted position by the scar Sas shown in Fig. 4 -the firearm may be rendered absol lutely safe by rotating the safety catch S- into the Vposition shown in Figs. 1, 3 and 4 .wherein it locks the scar in engagement with 'the bolt. To re the gun the handlev 15 of the safety catch S is rotated downwardly through anv arc of 18() to the posi-g tion shown in Fig. 6 wherein the sear is'V wholly disengaged from the catch. U n

pulling the triggerT the disconnector is moved upwardly, the projection 9 on the disconnector engagesthe surface 10 on` the sear (Fig. 6) to move the sear out of engagement with the bolt, and .the bolt is urged forwardly. into firing position by the spring 46 As fully described in my prior application Serial No. 282,642, the further operation of thegun is automatic,vthe bolt being locked in firing position by thelock 47, the firing member 48 being automatically ad-4 vanced relatively to the bolt to tire the car` tridge, the bolt being automatically retracted by the breech pressure when thev pressure has decreased. 'to a relatively4 low value, the spring 46 again advancing the bolt, and so on until all ofthe cartridges in the magazine have been fired or until the trigger T has been releasedlf Upon releasing the trigger at any instant the sear S engages the bolt when in retracted position and stops the firing.l When theA magazine .Ml (Fig.l 4) becomes empty the-projection 12 on th follower 13 engages the forward endll of yoke Y and rotates the yoke Y in a clockwise direction into the position showniin Fig. '4, thereby rotating the disconnector D into the `pos1tion shown in Fig. 4 wherein it disengages the sear S and permits the sear to be` moved, by means of spring 5, into position to engage the bolt when it is in retracted positionvafter firing thelast cartridge. Thus when the magazine becomes empty and the firing ceases the closure is automatica be evident that maga-zines of radically dif# ferent types may be attached to the rearm without employing any special adaptor and that a single catch serves to hold a magazine ofeither type in position.
